Climate Data Projections

The climate science community sources a suite of global climate models to help decision makers understand the projections of future climate change and related impacts, among the most widely used are the Coupled Model Intercomparison Project, Phase 5 (CMIP5) models included in the IPCC's Fifth Assessment Report (AR5). Key projected climate trends are summarized below:

Temperature

  • By mid-century the South African coast will warm by around 1 to 2°C and the interior by around 2 to 3°C.
  • By 2100, warming is projected to reach around 3 to 4°C along the coast, and 6 to 7°C in the interior.

Precipitation

  • This temperature increase will cause many parts of the country to become drier and thus experience a decrease in water availability.
  • Climate model suggests that the western and interior parts of the country are likely to become drier, and the eastern parts of the country wetter.

This section provides the options to visualize climate variables and indices derived from scientifically vetted CMIP5 projections for different timeframes, statistics, emission scenarios, and climate models.
